The indicative schedule of the PRACE Calls for Proposals for Preparatory Access is as follows.
| Action | Types A & B | Type C and D |
|---|---|---|
| Proposal submission | Continuously open | Quarterly cut off dates – 1st working day of the quarter (March; June; September; December) |
| Administrative validation | 2 working days after submission | 2 working days after the cut-off date |
| Review of proposals & decision | Up to 2 weeks after submission | Up to 2 months after submission |
| Access start date | Up to 2-3 weeks after submission | Access is provided starting approx. 45-60 calendar days after the cut-off date. Please note that access of the December cut-off date may be slightly delayed due to Christmas break. |
The process to access resources after the communication of the decision on allocation is two-fold:
- Awardees are asked to confirm their availability and readiness to use the awarded resources during the stated period of time
- Access is provided after receipt of a positive reply.
The allocation decision, including the type of access, start/end dates, duration and the resources awarded is not open for negotiation.
As detailed in the Terms of Reference of the Call for Proposals for Preparatory Access, “the award of Preparatory Access proposals of Types A, B, C and D is limited by the amount of resources available. For type C and D, there are also limitations regarding the availability of the support from experts (in terms of staff hours) and the type of expertise required.”
In case of oversubscription of a particular resource, resources will be awarded on a first-come, first-served basis to suitable proposals based on the submission date until the resources are exhausted.
